AIEX Fitness Tracker

This fitness tracker has a heart rate monitor smart watch with connected GPS tracker, 14 Sports Mode. It lets you read your messages and is even waterproof

It should be worn all day to record activities such as steps, distance, calories burned, active minutes and how you have slept.

This means you can keep track of how much you're moving throughout the day and ultimately find out how fit you are.

Helen says: "I certainly think fitness trackers have a role to play. It makes you a bit more mindful of what you're consuming and your calorie allowance. It also helps with your recommendation of 1,000 steps a day."

Kitchen Safe: Time Locking Container

This product works to banish temptation - by locking your favourite foods away in a kitchen safe.

The box can be locked for any amount of time between one minute and ten days - giving you a countdown until your next treat.

It has been compared to a pet food timer feeder and is available in three different sizes.

Helen says: "If you're struggling then one of these gadgets will help but there is obviously no substitutions for addressing your eating habits and overhauling your diet. Sometimes people just need a little bit of help to get them on their way."

This bracelet aims to put an end to bad habits by associating them with pain.

Based on aversion therapy, Pavlok offers owners the chance to 'shock' themselves, ranging from slightly painful to very sore depending on the intensity.

It ranges from between 50 and 450 volts - with results likely to be visible in five days.

Helen says: "I have heard about this in regards to smoking, but in terms of stopping yourself eating unhealthy snacks I don't know how much evidence there is. At £179.99 that is quite a lot of money to spend without the evidence that it will change your behaviour."
